3,6-Dibromo-7-ethyl­amino-4-methyl-2H-chromen-2-one

In title compound, C(12)H(11)Br(2)NO(2), the coumarin ring system is almost planar, the two rings being inclined to one another by 1.40 (15)°. There are two short intra­molecular inter­actions (N—H⋯Br and C—H⋯Br) involving the Br atoms. In the crystal, mol­ecules stack along the a-axis direction via...

description In title compound, C(12)H(11)Br(2)NO(2), the coumarin ring system is almost planar, the two rings being inclined to one another by 1.40 (15)°. There are two short intra­molecular inter­actions (N—H⋯Br and C—H⋯Br) involving the Br atoms. In the crystal, mol­ecules stack along the a-axis direction via π–π inter­actions; the centroid–centroid distances vary from 3.6484 (19) to 3.7942 (19) Å.
